Bu çalışmada geleneksel fermente Türk sucuklarından izole edilmiş toplam 50 adet koagulaz-negatif Staphylococcus (KNS) ve 10 Macrococcus caseolyticus suşlarının biyofilm oluşturma özellikleri fenotipik olarak belirlenmiş aynı zamanda suşlarda oluşumu ile ilişkili genler adezyon genlerinin varlığı multipleks polimeraz zincir reaksiyonu (mPZR) araştırılmıştır. Fenotipik slaym (slime) üretimi Cong...

Our previous study (Z. X. Peng et al., Carbohydr. Polym. 81:275-283, 2010) demonstrated that water-soluble quaternary ammonium salts, which are produced by the reaction of chitosan with glycidyl trimethylammonium chloride, provide chitosan derivatives with enhanced antibacterial ability. Because biofilm formation is believed to comprise the key step in the development of orthopedic implant-rela...

The aim of the study was phenotypic and genotypic analysis of 132 S. aureus strains isolated from mastitis in eastern Poland in respect to their biofilm formation ability. The analysis of the size polymorphism of fragment X in the gene encoding protein A (spa) revealed high genetic differentiation of the analyzed group of isolates. The ability of biofilm formation by the isolates was tested usi...

The aim of the study was to evaluate the effect of cadmium exposure on Staphylococcus epidermidis (ATCC 35984) biofilm formation. Bacteria were cultured in the absence or presence of different concentrations (0-50 µM) of cadmium. Biofilm formation and bacterial viability were assessed. Quantitative Real Time-PCR (qRT-PCR) was used to determine the mRNA expression of molecular markers of S. epid...

Biofilm formation is of growing concern in human and animal health. However, it is still unclear how biofilms are related to mastitis infections in dairy cattle. In this study, a comparison between two tests for biofilm formation and the association between biofilm and the presence of genes associated with biofilm formation were investigated for 92 Staphylococcus aureus isolates from clinical m...

conclusions prevalence of fbe and aap was significantly different from similar studies, yet frequency of bhp was in accordance with other studies. prevalence of icaa and is256 was not significantly different from some studies while a significant difference was observed when results were compared with some other studies. results of the 59 s. epidermidis, fbe was found in 89.8%, while aap and bhp...
